     [ https://issues.apache.org/jira/browse/HADOOP-13552?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe updated HADOOP-13552:
--------------------------------
    Attachment: HADOOP-13552.001.patch

Attaching a patch that changes the warning log to a debug log in case this is still useful for debugging why the invocation handler isn't retrying when it should.

> RetryInvocationHandler logs a warning for any exception that it does not retry.  There are many exceptions that the client can automatically handle, like FileNotFoundException, UnresolvedPathException, etc., so now every one of these generates a scary looking stack trace as a warning then the program continues normally.
